MQXLite and USB

Hi,

I am using PE 10.4.2 and am trying to add MQXLite to an existing project. The project has fsl_usb_framework and is generating the error below:

How do I fix this error?

Thanks

Paul

Hello Paul,

I suppose you have PEx + KSDK project and you have selected MQX operating system in the fsl_os_abstraction component. There is selected "MQX Lite" in the mqx_ksdk component by default (inherited component of fsl_os_abstraction).

To fix this issue, open the Component Inspector of the mqx_ksdk component and select "MQX Standard" in the "Configuration parameters > Configuration set" property, see the screenshot below:

Please note, that this change also require reconfiguration of the project (fsl_debug_console component is not allowed in the project (it is integrated in the MQX Standard component) and one instance of OS_Task component is requested at least).

Best Regards,

Marek Neuzil

Thanks Marek,

I was trying to keep the MQX OS code size to a minimum. Is there a way to reduce the footprint of MQX?

All we require is some simple task management. The peripherals use eDMA from PE.

Hello Paul,

You can find details about MQX and MQX Lite on the web page Freescale MQX™ Software Solutions|Freescale

There is also following overview:

	MQX™ RTOS 4.x	MQX™ Lite RTOS	MQX™ RTOS for Kinetis SDK
Delivery Mechanism	Traditional installer with full source	Processor Expert (PEx) component	Traditional installer with full source
I/O Drivers	MQX peripheral drivers; PEx driver optional	PEx drivers only	Kinetis SDK drivers
Configurability	User selects needed services from full or lightweight versions	Reduced services only; lightweight options only	User selects needed services from full or lightweight versions
Components	Kernel, TCP/IP stack, USB stack, file system, middleware. Includes own peripheral drivers.	Kernel only. Peripheral drivers provided by PEx.	Kernel, TCP/IP stack, USB stack, file system, middleware. Peripheral drivers provided by Kinetis SDK.
Availability	Select Kinetis K Series, Vybrid, select ColdFire, select Power Architecture	Kinetis L Series, Kinetis K Series, select Kinetis E Series	Kinetis MCUs supported by Kinetis SDK

The mqx_ksdk component contains following options that can be used for minimizing of the code size. There is also possible to write own user definitions, see the User settings > Definitions.

Note:

All definitions are generated in the generated header files (user_config.h and mqx_sdk_config.h).

You can also select the BareMetal OS in the fsl_os_abstraction component. This options is also supported by fsl_usb_framework and allow also a simple tasks management.
